4s³™:
Semi-Automated Heat Sealer

The 4s3™ is a semi-automatic thermal sealer which is compatible with a wide range of seals and plates of differing designs and heights.

With variable temperature and time settings, sealing conditions are easily optimised to produce a 100% seal, eliminating sample loss.

Plate and seal are placed on the holder, the "Operate" button pressed and the drawer automatically closes. The sealing process is controlled by an electric mechanism. This unique feature eliminates operator variation, giving a consistent seal every time and reducing the damage caused to microplates by over-sealing.

Real Time Display

The rapid heating element allows for a quick start up within minutes.

The temperature is displayed in real time so that the heating up process can be monitored.

Energy Saving Functions

When the unit is left idle it automatically switches into standby mode, during which the temperature of the heating element is reduced to 60°C to save energy. When the sealer is left idle for longer periods it switches off automatically for added safety. The times at which the unit switches into standby and switch off modes can be adjusted to suit the user’s needs.

Adapters and Sealing Aids

The 4s3™ employs a unique and cost saving adapter system. Deep well plates and most other skirted plates can be sealed on the standard plate carrier (4ti-0615, supplied with the unit). For all 96 well PCR plates an additional plate carrier (4ti-0625, optional extra) must be used. Both plate carriers can also be combined for easier handling of shallow well plates such as 384 well PCR plates.

For better sealing of those films which have a tendency to curl, 4titude offer sealing aids. A weighted platen (4ti-0602) for use with deep well blocks is provided with the unit and a sealing frame for use with all other plate designs is supplied when ordering the optional 4ti-0625 adapter.
